Altering grip width. Keeps muscles guessing. ( On bench press and chin ups. )
Tuning out people around you helps. My worst injury was my left shoulder when I was benching and I let some shit talk directed at me, by total strangers piss me off. I pushed through a bad lift. Took 3 months for the pain to go away, with weekly visits to the physio. I go to the gym off peak since then.
cheers.
